XSTREAMIS PLC MAC prefixes: vendor identified, device unknown
Summary
- // what this is
- Xstreamis is registered to MAC prefix
00:B0:B3and 1 more in the IEEE OUI database. When a device's MAC address begins with00:B0:B3, that block was registered by Xstreamis — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
About this vendor.
A MAC address beginning 00:B0:B3 or 00:10:87 matches an IEEE MA-L assignment to XSTREAMIS PLC; the assignment does not identify a particular device. The supplied IEEE records contain two full 24-bit prefixes, both registered to that exact legal name. They do not establish the company’s products, industry, country, current identity, or whether either prefix appears in deployed equipment.
Each prefix fixes the first 24 bits, leaving 24 suffix bits and 16,777,216 possible suffix values per prefix. This is a mathematical address-space count, not a device or shipment count. In both literal prefixes, the first octet is 00: its Group bit (01) and Local bit (02) are both zero. Changing either bit changes the prefix, so addresses with a changed bit do not match these exact prefixes.
RFC 7042 explains the role of these bits in MAC identifiers and the relationship between prefixes and remaining identifier bits.
A matching capture supports only that the address begins with a registered prefix. It does not prove the specific device, product, operating system, traffic prevalence, or security state. Assignment dates are unavailable in these IEEE CSV records.
